A deposit isn't being categorized despite being the same as always. App says date is incorrect (1900-...) Please help

I know a couple of troubleshooting steps to resolve the issue, timmysgirl38.

There are instances when the app has a large amount of data, resulting in strange results. You can fix this by clearing the app's cache.

To clear the cache in your QuickBooks Online app, you can follow the steps below:

• Android - Select the Menu at the bottom and click the Settings icon. Then pick Refresh Data and choose Yes.
• iOS - Tap the Menu at the bottom and click on Help & Feedback. Then select Refresh Data and Refresh.

To clear cache in your phone settings:

• Android - From your phone's Settings, select Apps (varies by device). Choose the QuickBooks app from the list and pick Storage, then Hit Clear data.

• iOS - From your phone's Settings, choose Settings. Click on General and choose iPhone Storage. Select an app that's taking up a lot of space. To free up the Storage without deleting the documents and data for the app, select Offload App.
